How Did Covid Affect Seattle Housing Price
Executive summary
The goal of this time series project is to address the question: “How did Covid affect the housing price in Seattle”. The data set is obtained from Zillow, and it contains monthly housing price data. A variety of techniques was used: the data set was first splitted into training and testing set; then the series is differenced to remove trend and seasonality; two model was fitted given the sample ACF/PACF; A series of diagnostic checking tests are performed to the models.
The project then proceeds with the better model, and performs forecasts using the best model. Turns out a heavy tail distribution might be more desirable to fit this data set. However, given the best model in this project, Covid affected Seattle’s housing price in a negative way.
All these steps are covered in detail in the main body of the report below:
